| Street only or track? Drag or road course? Different activities, different strains on the chassis. My black vert (350 rwhp, 350 tq) has a very slight twist to it ( clockwise from the front of the car - not really visible but measurable when installing coilovers). It has about 80k miles on the chassis, about 15 since the swap. About 1 to 2k of those are track and autocross. The flex on verts is material on the track, and when the rear goes, she really goes if you know what I am saying. Personally I wouldnt bother going higher than around 500 unless you just want a dyno queen or to go fast for short bursts in a straight line or on the highway.
